homomorphism (plural homomorphisms)
- (algebra) A structure-preserving map between two algebraic structures of the same type, such as groups, rings, or vector spaces.
- A field homomorphism is a map from one field to another one which is additive, multiplicative, zero-preserving, and unit-preserving.

- This motivates a generalization, and exponential homomorphisms are now defined, in an algebraic fashion, from certain free products to formal power series rings with non-commutative indeterminates.

- Definition 1.15. Let and be matrix Lie groups. A map from to is called a Lie group homomorphism if (1) is a group homomorphism and (2) is continuous.
